Abstract
The utility model provides a counterface has a little, and figurative carbocycle seals belongs to fluid movive seal field, this carbocycle internal surface of characterized by has little molding along circumference evenly distributed, and little molding is along circumference evenly distributed at the carbocycle internal surface. The utility model discloses can be through opening little figurative structural design on the carbocycle terminal surface, the fluid hydrodynamic effect that the groove of modelling a little under high -speed high -pressure operating mode produced realizes the non -contact, the film lubrication is guaranteed in little figurative solid oil effect under the low -speed operating mode to reduce the friction and wear of carbocycle and axle, improve its performance and life -span.
Description
Technical field
The utility model relates to a kind of carbon ring seal, is specifically related to the carbon ring seal of a kind of counterface with micro forming, belongs to fluid movable sealing field.
Background technology
In slewing, carbon ring seal, for the axle head auxiliary seal in early stage of oil film seal, is the crucial potted component of reducing pressure by regulating flow, directly affects the sealability of primary seal and the safe handling of equipment. In actual use procedure, the normal floatability because of preposition auxiliary sealing carbon ring seal is poor causes seal failure, and even affects whole equipment. Its failure mode is not possess good floatability to cause seal and axle serious wear, and this wear out failure depends on the unsteady performance of carbocyclic ring.
Utility model content
In view of this, the utility model provides the carbon ring seal of a kind of counterface with micro forming, can be by the micro forming design of end face, under high speed and high pressure operating mode, micro forming groove produces hydrodynamic pressure and realizes noncontact, under low speed operating mode, the solid oil effect of micro forming ensures film lubrication, thereby reduce fretting wear, improve serviceability and the life-span of seal.
Counterface is with the carbon ring seal of micro forming, it is characterized in that: comprise micro forming, rotating shaft, carbocyclic ring, stop pin, axle sleeve, spring leaf, housing, described carbocyclic ring inner surface has micro forming, described micro forming is evenly distributed on the inner surface of carbocyclic ring, described carbocyclic ring is circumferentially limited by a stop pin, do not rotate with axle sleeve, described carbocyclic ring is axially being compressed on housing by a spring leaf.
Above-mentioned counterface, with the carbon ring seal of micro forming, is characterized in that, described micro forming is circular hole, and radius is 1-4mm.
Above-mentioned counterface, with the carbon ring seal of micro forming, is characterized in that, described micro forming center distance 2-8mm.
Above-mentioned counterface, with the carbon ring seal of micro forming, is characterized in that, described micro forming is along rotor shaft direction distribution 1-3.
Above-mentioned counterface, with the carbon ring seal of micro forming, is characterized in that, described micro forming center is to carbocyclic ring A, B end face distance 1-2mm.
Above-mentioned counterface, with the carbon ring seal of micro forming, is characterized in that, described micro forming shape can be circular hole, tri-angle-holed, diamond hole, rectangular opening.
Above-mentioned counterface, with the carbon ring seal of micro forming, is characterized in that, described micro forming arrangement mode can be parallel with rotor shaft direction, with the axis α that has a certain degree, 0 °≤α≤90 °.
Beneficial effect: counterface utilizes the hydrodynamic effect of micro forming when the high speed with the carbon ring seal of micro forming, when low speed, dynamic pressure effect weakens, but because the existence of end face micro forming ensures film lubrication, thereby reduce fretting wear, improve the serviceability of seal.

Detailed description of the invention
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, the utility model is described in detail.
As shown in Figure 1: this counterface comprises micro forming 1 with the carbon ring seal of micro forming, rotating shaft 2, carbocyclic ring 3, stop pin 4, axle sleeve 5, spring leaf 6, housing 7.
As shown in accompanying drawing 2 and accompanying drawing 3, the utility model provides the carbon ring seal of a kind of counterface with micro forming, and this carbocyclic ring inner surface has been uniformly distributed circumferentially 60 micro formings 1, and micro forming is uniformly distributed circumferentially at carbocyclic ring inner surface.
Each micro forming 1 is the circular hole that radius is 1mm, and the aspect ratio of micro forming 1 is 0.001.
The distance of center circle of the next micro forming 1 of distance of center circle of each micro forming 1 is from being 2mm. The distance of center circle carbocyclic ring A of each micro forming 1, the distance of B end face are 1mm.
The arrangement form and the size that adopt above-mentioned micro forming, can reduce the fretting wear between carbocyclic ring and axle.
As shown in Figure 1, the operation principle of the sealing carbocyclic ring of the present embodiment is that carbocyclic ring 3 is circumferentially limited by a stop pin 4, can not rotate with axle sleeve 5, axially has a spring leaf 6 at media end, and carbocyclic ring 3 is pressed on housing. In the time that equipment shuts down, due to self gravitation, carbocyclic ring 3 meeting free suspensions are in rotating shaft, and in the time of device start, rotating shaft 2 rotarily drives carbocyclic ring 3 and rotates, and under the effect of centrifugal force, forms liquid film in gap.
Counterface utilizes the hydrodynamic effect of micro forming 1 when the high speed with the carbon ring seal of micro forming, when low speed, dynamic pressure effect weakens, but because the existence of end face micro forming 1 ensures film lubrication, thereby reduce the fretting wear between micro forming 1 and axle 2, improve the serviceability of seal.
Content described in this description embodiment is only enumerating of way of realization to utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also and in those skilled in the art is conceived thinkable equivalent technologies means according to the utility model.
